Board Export: Option to export the cards for a specific custom field as reports#69

As a user, I wish to have the option to export the board and get the report of cards information for a custom field.

Scenario:
We have a custom field that is visible on the face of each card. This custom field represents who we are selling our product through. I am hoping to create the reports for this custom field that would include each cards for that custom field and the information from each card.
There may be other information from the card that we want to show as well.
